Abstract

TiO2 is the most widely used photocatalytic material.To improve its photocatalytic performance,semiconductors coupling modification is an effective method.The energy band position of SrTiO3 is matched with that of TiO2,which can effectively inhibit the photoelectron and hole combination,therefore,the SrTiO3/TiO2 composite materials show good photocatalytic performance.The research progress on the commonly used preparation methods and photocatalytic property of SrTiO3/TiO2 at home and abroad was first summarized.On this basis,the ion doping,precious metal modification and semiconductors coupling modification processes of SrTiO3/TiO2 were reviewed.
